“…More generally, the concepts developed for cold Rydberg gases could tap into new potential for other physical settings, and may indeed open up new regimes of length and energy scales that are not accessible with cold Rydberg atoms. Indeed, recent work suggests that such diverse settings as thermal vapour cells (Honer et al, 2011;Ripka et al, 2016), semiconductor excitons (Kazimierczuk et al, 2014) or nanophotonic structures (Douglas et al, 2016;Shahmoon et al, 2016) provide a very positive outlook for future explorations. Surely, the range of exciting questions and perspectives will make Rydberg-EIT an active field of research for years to come.…”

Coupling light to ensembles of strongly interacting particles has emerged as a promising route toward achieving few photon nonlinearities. One specific way to implement this kind of nonlinearity is to interface light with highly excited atomic Rydberg states by means of electromagnetically induced transparency, an approach which allows freely propagating photons to acquire synthetic interactions of hitherto unprecedented strength. Here, we present an overview of this rapidly developing field, from classical effects to quantum manifestations of the nonlocal nonlinearities emerging in such systems. With an emphasis on underlying theoretical concepts, we describe the many experimental breakthroughs so far demonstrated and discuss potential applications looming on the horizon

“…A prominent example where the increase in storage lifetime can have impact is the Rydberg-vapour based single-photon source [22]. Recent storage times with light stored as Rydberg excitation in thermal vapour yields lifetime of the memory of only about 1.2 ns [23], limited by atomic-motion induced dephasing of the spinwave imprinted by the two-photon excitation. In order to obtain single photons from the output, one usually relies on strong blockade, assuming that multiple excitations will dephase on the timescale of the excitation laser pulse [22,23] due to atom interactions causing level shifts of C α /r α for atoms at distance r interacting with resonant dipole-dipole (α = 3) off-resonant van der Waals (α = 6) interactions.…”

Dressed-state electromagnetically induced transparency for light storage in uniform-phase spin waves

et al. 2016

We present, experimentally and theoretically, a scheme for dressed-state electromagnetically induced transparency (EIT) in a three-step cascade system where a four-level system is mapped into an effective three-level system. Theoretical analysis reveals that the scheme provides coherent state control via adiabatic following and provides a generalized protocol for light storage in uniform phase spin-waves that are insensitive to motional dephasing. The three-step driving enables a number of other features including spatial selectivity of the excitation region within the atomic medium, and kick-free and Doppler-free excitation that produces narrow resonances in thermal vapor. As a proof of concept we present an experimental demonstration of the generalized EIT scheme using the 6S 1/2 → 6P 3/2 → 7S 1/2 → 8P 1/2 excitation path in thermal cesium vapor. This technique could be applied to cold and thermal ensembles to enable longer storage times for Rydberg polaritons.

“…In these types of devices, Rydberg atoms are directly prepared from an ensemble of ground state atoms at moderate vapor pressures inside dielectric environments (borocilicate glasses or quartz) near room-temperature. These Rydberg atoms can be excited and proved either by cw multi-level electromagneticallyinduced-transparency (EIT) 32,33 or through pulsed nonlinear spectroscopy schemes such as four-wave-mixing 34,35 .…”

Rydberg-atom-enabled atomic vapor cell technologies show great potentials in developing devices for quantum enhanced sensors. In this paper, we demonstrate laser induced DC electric fields in an all-glass vapor cell without bulk or thin film electrodes. The spatial field distribution is mapped by Rydberg electromagnetically induced transparency spectroscopy. We explain the measured with a boundary-value electrostatic model. This work may inspire new ideas for DC electric field control in designing miniaturized atomic vapor cell devices. Limitations and other charge effects are also discussed.
